A power outage leaves Chandler stranded in an ATM vestibule with Victoria's Secret model Jill Goodacre, whom he desperately tries to impress, Ross tries to ask Rachel out on a date, and Joey learns that Monica used to be infatuated with him.

Joey falls for Phoebe's twin sister, Ursula, making Phoebe feel neglected. Ross has doubts about parenthood when he attends Lamaze classes with Carol and Susan. Meanwhile, Chandler finds himself between a rock and a hard place, when he is told to fire an employee he is attracted to.

The gang searches frantically for Marcel, who slipped out of the apartment while Rachel was baby-sitting him. Just as it looks as though Rachel and Ross might actually spend a romantic evening together, her ex-fiancé barges in and declares his love for her.

After Mr. Heckles dies and leaves all his belongings to Monica and Rachel, Chandler discovers eerie similarities between the late eccentric man and his own life. Ross and Phoebe have a dispute over the progression of evolution.

When Janice asks the gang if any of them have ever slept together, the friends flash back to a time three years before.
